Problems with GNU radio in Cygwin

GNU Radio
1

More Detail Provided:

I am installing GNUradio version 3.2 into Cygwin running Windows XP. I
am using the tarball source for wxPython version 2.8.10.1. I have
unpacked the source and successfully compiled it, built and installed
wxWidgets, built and installed wxPython and tested it successfully. I
did have to copy the python2.5/site-packages from /usr/lib/local to
/usr/local/lib/python2.5/site-packages. I then continued with the 3.2
install of GNUradio. I had to get and install the 1.38 version of
Boost. I unpacked the the tarball for GNUradio 3.2 and ran the
following commands in the /usr/src/gnuradio-3.2 directory to perform an
full installation of GNUradio:

./configure
make
make check
make install.

I received some warnings but no errors and the setup and install
completed. When I cd my working directory to
gnuradio-examples/python/audio to run the test audio program is when I
received the following error:

cd /gnuradio-examples/python/audio

python dial_tone.py
Traceback (most recent call last):
File “dial_tone.py”, line 23, in
from gnuradio import gr
ImportError: No module named gnuradio

This is where I am stuck. Any help would be gladly appreciated.

This the error I received when testing the GNU Radio installation after
the make file finished running.
I have Boost 1.38 loaded along with GNU Radio version 3.2 and wxPython
version 2.8.10.1. All the paths have been setup.

$ python dial_tone.py

By default, python looks in /usr/lib/python2.5/site-packages for a
directory
called “gnuradio”. Is it there? To find where your build put gnuradio,
run
the command

fgrep pythondir config.status

in your build directory and look at the value of “pythondir”. Does it
say
/usr/lib or /usr/local/lib? Is gnuradio there? If gnuradio is in
/usr/local/lib/python2.5/site-packges, did you set PYTHONPATH?

Did you run ldconfig (or similar) after make install?

Don,
I have the python2.5 site-packages installed in both /usr/lib and
/usr/local/lib directories. Which PYTHONPATH should be used? First the
setup documentation tells you to set the path to
/usr/lib/python2.5/site-packages, when wxPython (python) then it
changes to /usr/local/lib/python2.5/site-packages once you run the
config, make, and make install for the GNUradio software.

Which one contains the directory “gnuradio”?

Which PYTHONPATH should be used?

The one that contains gnuradio.
